Android does OCR natively as well. Drag up from the bottom part way (the gesture that opens the view that lets you scroll left and right through all your open apps) and then press and hold on some text and you'll be able to select and copy text being displayed by one of your apps.
Oh that would be interesting. Can you say more? I tried on a Samsung S7 but I can't seem to do it. Maybe it's a later Android version, last time the S7 was updated it was with v8 o_O
